Underworld King Fights For His Wife

Lu Chen is the master of a secret order, powerful enough that his subordinates command whole cities. After he meets the woman he marries, he keeps all of that hidden and takes a job as a laborer on a construction site so the two of them can live ordinarily. On their wedding anniversary he waits for her at home. She is at a rich family's house, celebrating the birthday of a young nobleman there. He files for divorce. At a banquet afterward he is pushed to the edge of the room and mocked by the other guests. A powerful lord arrives and treats him with deference, and Lu Chen states who he actually is. The crowd does not believe him until his own men come through the door. He then moves against the young nobleman's sister and against one of the great houses of the capital. His ex-wife had attached herself to that family.
